#### Execution Tab - Self Centering Point Strategy

Use the Execution tab for the Self Centering Point strategy to override the global machine motion values that are specified on the Motion tab in the Parameter Settings dialog box (Edit | Preferences | Parameters):

Sample Execution tab

By default, the probe tip radius is not compensated for the self-centering point. The measured point is the center of the ruby tip.

Override Motion Parameters

If you want to use motion values that are different than the global machine motion values, select this check box.

Prehit

Type the distance away from the theoretical hit location on the surface where PC-DMIS starts searching for the part. For more information, refer to "Prehit Distance" in the "Setting Your Preferences" chapter in the PC-DMIS Core documentation.

Retract

Type the distance the probe retracts from the surface after it takes a hit. For more information, refer to "Retract Distance" in the "Setting Your Preferences" chapter in the PC-DMIS Core documentation.

Check Distance

Type the distance past the theoretical hit location that the machine continues to search or check for the surface of the part. This distance is after it traverses the Prehit Distance value. For more information, refer to "Check Distance" in the "Setting Your Preferences" chapter in the PC-DMIS Core documentation.
